Have to agree. Recently I used a Windows 8 Samsung tablet at a Microsoft Store. As much as I love Microsoft, I still feel the whole Metro paradigm is a slight mistake. They are closing the doors to the tried-and-true interface that Windows users have grown to love by trying to wall people into Metro. Frankly, "Desktop" is almost unusuable without a Start Menu button. You can't get into Computer Properties easily (usually right-click Computer on Start Menu). Control Panel is not obvious. It's virtually impossible to pin things on the dock unless you can find a way to open them. Businesses aren't going to upgrade unless someone uses a touch-screen or tablet (and even then it's doubtful).
They should be trying to make users WANT to use Metro--instead of forcing them into it. It's beautiful, great for tablets, and has the apps people crave. I'm not sure what they mean by "tested and ready", because I can't be the only person who has brought this up on the Internets and I'm sure they've discussed this internally. As a Windows-fan, they're losing me. And like in politics, if you've lost your base, you've lost.
